TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 375,815, dated January3, 1888.

(No model.)

To aZZ whom it may concern.-

Be it known that I, MARTINE. HERSHEY, of Harrisburg,in the county ofDauphin and State of Pennsylvania, have invented certain new and usefulImprovements in Traction-Engines or Road-Rollers; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, forming a partof this specification, and to the figures and letters of referencemarked thereon.

My improvements have relation to the construction of the boiler andwater-tanks of machines of this class, and will be first described atlength, and the novelty of them will be then particularly pointed out inthe clauses of claim at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective view of aroad-roller embodying mysaid improvements. Fig. 2 is an end view, andFig. 3 a top plan view, of a portion of the machine, showing theconstruction of the tanks. Fig. 4 is a side elevation of the connectionbetween the tank and boiler or fire'box.

Similar letters of reference in the several figures indicate the sameparts.

The letter A indicates the boiler, 13 the main axle, and M theground-wheels. An extension-sheet, K, is bolted or otherwise secured tothe boiler or fire-box extension, and extends rearward and aroundu nderthe fire-box, being provided with an'opening or openings,L, for thedischarge of the ashes and einders raked from the latter. To the rear ofthis extension-sheet, at a point behind the ground-wheels M M of themachine, a tank, N, is secured, preferably by flanges or angle-irons, asshown in Fig. 3.

The tank is constructed of U shaped form, so as to leave a centralpassage-way, 0, through which access to the fire and ash-pit can bereadily had. One of its compartments may be used for carrying water andthe other for fuel; or both may be employed for either purpose, asdesired.

By reason of the curved or circular form of the extension-sheet K, averyrigid connection is made between the boiler and tank without unnecessaryweight of material.

A wooden or metal platform, P, is preferably arranged in the passage-wayover the extensionsheet, for the engineer to stand upon.

Having thus described my invention, what I claim as new is-- 1. In atractionengine or road-roller, the combination, with the boiler, of atank rigidly connected thereto, having the central passage way andthe-upwardlyextending side port-ions, substantially as described.

2. In a traction-engine or road-roller,a tank rigidly connected to theboiler and constructed of U form, so as to afford aconvenientpassagewayto the firebox, substantially as described.

3. The fire box having an extension-sheet passing around its bottom andextending to the rear, in combination with a tank or tanks attached tosaid extension-sheet, substantially in the manner described, and for thepurpose specified.

4. The combination, with the fire-box. ofthe curved extension-sheethaving the opening for the discharge of cinders and ashes drawn from thefirebox, and the U-shaped tank secured to said extension-sheet,substantiall yas described. 5. The combination, with the fire-box, of thecurved extension-sheet, the U shaped tank secured to it, and theplatform in the housing over the extension-sheet, substantially asdescribed.
